VITAL – Vehicle-Actuated Intelligent Traffic Signal Control
VITAL – Vehicle-Actuated Intelligent Traffic Signal Control
Idea
Intelligent control methods for traffic light systems (TLS) are an important element of traffic control. Within this project, two novel TLS-control procedures that were developed by the German Aerospace Center (DLR) will be evaluated in the field. The new methods are designed to utilize especially the data that stem from new data acquisition methods like vehicle-to-infrastructure communication, video or probe vehicle data.
The usage of these data is the main innovation of these methods; instead of using surrogate measures like the time headway for control, they use directly the loss times as measured by the vehicles. So, in principle, they do not need any additional infrastructure at all which saves infrastructure costs and allows a short-term to market.
Within simulation it could be shown, that the two new algorithms to be applied in the field within this project will help to solve current transport and climate policy issues:
Reduce waiting and travel times for road users,
Avoidance of pollutant emissions in terms of climate protection and
Reduce financing costs for the infrastructure by the municipalities.
Content
The two methods are covered by patents and have been shown so far in simulations with DLR’s microscopic traffic simulator SUMO and the commercial software VISSIM to be superior to the existing methods. So, the goal of this project is to test them in the field to validate them and to demonstrate their technical feasibility. This will be done into two or three test fields, where the existing TLS infrastructure (sensors and actuators) are used and complemented by the new technologies. In addition, these test fields have been equipped with sensors that help in validating the new methods.
The VITAL project is divided into 5 work packages and an additional project management:
